HYDROCARB ON-BURNER.

Patented Apr. 16, 1918.

Application filed June 27, 1917. Serial No. 177,254.

To aZZ rv/i012; it may concern.

Be it known that I, FRANK-A. NIEBERD- at. Cleveland, in the county of Guyahoga and State of Ohio, have invented a certain new and useful IHIPI'OVCIHGllt in Hydrocarhon-Burners. of which the followin is a full, clear, and, exact description.

This invention relates to the kind of hydro-earb m burners 111 which a wick 1s "used to draw the fuel up to the lower end of an annular combustion chamber.

The invention consists in the constructionv 'and combination of parts 'WlllCll prevent the raising of the wick above a predetermined level, and by which the combustion tubes may be raised. in order that the fuel at the is a plan view with top of the wick may be ignited, all as shown in. ,the drawing and hereinafter described and definitely, pointed out in the appended clanns. I n the drawings, Figure 1 is a central vertical section of aburner which embodies the Fig. 5 is an outside view of the spreader. Referrin to the -)arts b Y reference char acters, and 12 represent two concentric wick tubes; and 13 the tubular wick which is fitted to the annular space between them. 14 and 15 represent two concentric perforated combustion tubes, which are so connected together, as by the cross rod 16, that they may be raised and lowered in unison. When in operative position the outer combustion tube 14 embraces the upper end of the outer wick tube. and rests upon an annular flange 17 fixed to the latter; while the inner combustion tube rests on a horizontal shelf 21. which in turn rests upon the inner wick tube and has an upwardly extended marginal flange 22 which embraces the lower edge of said combustion tube.

The shelf 21 is the upper outwardly turned part of an inverted conical shell 20 which has a perforatedbottom 23 which serves as the diaphragm commonly found these spring arms, spread 14 and 15 must be raised.

in devices of this sort; while the conical wall of this shell serves as a spreader to hold in position the wick stop devices. There are a plurality of these wick stop devices arranged symmetrically around the axis of the wick tubes. Each consists of a spring arm 30 attached at its lower endto the inner wick tube, and lying within said wick tube and extending upward from its point of connection to'a point close to the top of the wick tube.

- The upper end of each of these arms is formed with an outwardly bent finger 31 which passes'through a slotin the wall of the inner wick tube, and overhangs the annular space between the two wick tubes. Preferably these wick stop spring arms 30 are all parts of a sleeve 33 through which they are fixed to and within the inner wick tube. Therefore if one should withdraw the conical shell 20 the ends of all of these spring arms would be drawn'inward and the fingers 31 would no longer overhang the annular space between the wick tubes. The wick may then be easily introduced between said wick tubes; but by inserting this conical shell into the upper end of the wick tube its conical surface will, by engaging all of outward into the operative position shown.

It will be noted that there is an annular groove 24 in the outer surface of the conical shell just below the shelf 21, and it will also be noted that each spring arm 30 is'bent so as to form adjacent its upper end an inwardly extended lug 34. The conical shell engages with the lugs 34 of the various spring arms as it is being inserted, and

these lugs when the conical shell is in place e ter the annular groove 24, and thereby aId in holding the conical shell immovable in the stated position.

In order that one may light the fuel at thetop of the wick the combustion tubes For this purpose there is a vertically movable rod 40 bent at its lower-end to form a cam arm 41. This rod may be raised by the action of an opcrating lever 42 which is pivoted on a vertical pivot on an car 44, shown by dotted lines in Fig. 3, fixed to the inner wall of the base member 43 of the device. This lever goes through a horizontal slot 45 in this base member and therefore it may swing only in the horizontal plane. When it is swungit will by engaging with the cam arm 41 raise this rod, which rod passes up through and-is guided by a hole in the central part 46 of the spider-like top of the base member 43. It likewise passes through and is guided through a hole in the perforated bottom of the conical shell; and its upper end goes into a vertical tube 51 which is part of a vertically movable lifter spider having a plurality of thin flat arms 52, which attheir ends have vertical edges which fit Within the inner combustion tube 15. There is a partition 18 fixed within the inner combustion tube, and it has a central circular opening 19. Each of the wings or arms 52 has an upwardly extended portion 53 which, when this lifter spider is raised, will enter and fit. Within the hole 19 in the plate 18, and therefore will aid in preventing any tipping of the combustion tubes when they are raised. It is obvious that Y when the rod 40 is raised its upper end will engage the end of the tube 51 and thereby the lifter spider will be raised, and after a short upward movement it will engage with and thereafter lift the combustion tubes.

. Having described my invention, I claim 1. The combination oftwo concentric wick tubes, a plurality of spring metal arms each of which is fixed at one end to a suit able support, and which has at its other end a laterallyextended wick stop finger adapted to overhand the annular space between the upper. ends of said wick tubes, and a movable device which engages all of said arms and holds them and their fingers in the stated operative position.

2. The combination of two concentric wick tubes, a plurality of arms connected at their lower ends with one of said wick tubes and having at their upper .ends laterally extended wick stop fingers, and a movable device adapted to engage all of said arms and holdthem in position such that their said fingers overhang the annular space between tubes, a plurality of arms connected at their lower ends with one of said wick tubes, and

drawn said arms will automaticallyrimcvew "into position such'tha't their fingers will not overhang said space between said wick tubes.

4. The combination of. two concentric wick tubes, a plurality of spring arms which are secured at their lower ends to and within the tube and have at their upper ends out- I,

Wardly turned wick stop fingers adapted t-o' overhang the space between said wick tubes, a spreader movable into said innerwick tube and into engagement with all of said arms to move them all outward into positions Such that their fingers will overhang the annular space between the wick tubes.

5. The combination of two concentric wick tubes, a plurality of spring arms which are secured at their lower ends to and within the wick tube and have at their upper ends outwardly turned'wick stop fingers adapted-to overhang the space between said wick tubes, a conical spreader having an outwardly turned flange which rest upon he inner wick tube,which spreader enters the space bounded by said arms and engages with them and moves them to and holds them in annular space between said wick tubes.

6. The combination of two concentric wick tubes, a plurality of spring arms which are secured at their lower ends to and withinthe wicktube and have at their upper ends outwardly turned wick stop fingers adapted tooverhang the space between said wick tubes, a conical spreader having an outwardly turned flange which rests upon the inner wick tube which spreader enters the space bounded by said arms and engages with them and moves them to and holds them in position such that theirfingers overhang the annular space between said wick tubes, said conical spreader having an annular groove just below said flange, and said arms having inwardly directed lugs which engage in said groove.

7 The combination of two concentric wick tubes, a plurality of spring arms which are secured at their lower ends to and within the wick tube and have at their upper ends outwardly turned wick stop fingers adapted to overhang the space between said wick tubes, a conical spreader having an outwardly turned flange which rests upon the inner wick tube which spreader enters the space bounded by said arms and engages with them and moves them to and holds them in position such that their fingers overhang the annular space between said wick tubes, said conical spreader having an annular groove just below said flange and said arms havin inwardly directed lugs which engage in said groove, and said conical spreaderhaving a perforated bottom.

8.The combination with a burner com prislng two concentric wlck tubes, two concentric combustion tubes supported above .5 shaped lower endand having its upper and within said closed spider tube, a'base mm her to which the wick tubes are secured,a lever pivoted to said base member, which base memberhas a slot through which the free end of said 'lever passes, said lever go- 10 ing beneath' and being 1n engagement with the cam-shaped lower end of said rod.

- In testimony whereof, I hereunto afiix my signature.
